WAGON AXLE AND HUB.

SPECIFICATION forming part of Letters Patent No. 442,353, dated December 9, 1890.

Application filed January 2, 1890. Serial No. 335,703. (No model.)

To @ZZ whom il; may con/cern: said core. This flange 8 is turned up smooth Be it known that I, ERNEST WILLIAM on the outer surface and grooved with a cy- COOKE, a citizen of the United States, residlindrical groove opposite the position and ing at Chicago, in the county of Cook and similar to the groove in the face of the plate 5 State of Illinois, have invented anew and usc- I. and this groove carries the metallic balls 55 ful Improvement in Roller-Boxes for Tagen 10. rIhe flange S is secured to the hub bythe Axles and IIubs, of which the following is a screws in the outer face. The body of the specification. core 9 is provided with wedgeshaped ribs D', My invention relates to roller-boxes for which enter the wood of the hub A and prelo wagon axles and hubs, in which a cage convent the core 9 from revolving. On the end 6o taining a series of cylindrical rollers is conof the core 0 farthest'from the flange S I cut tained within the core-box of the wagon-hub, a screw-thread, and to this screw-thread I seand which cage revolves about the axle, my cure a flange-plate U. The flange-plate 6 is object being to provide an axle and hub that turned down smooth on the outersurface and r 5 shall require the least possible amount of grooved to carry the metallic balls 7,inasimi 65 lubrication and at the same time give the larfashionto the ange S. Between the flangeleast friction. I attain this object by means plate 6 andthe flange a* is the bodyof the hub 0f the mechanism shown in the accompanying A, and at one end of the hub A, over Ithe flange drawings, in which-H 8, is secured a leather collar 14, held in place zo Figure 1 is a sectional view in the median by the screws 13 and fitting under the me- 7o line. Fig. 2 is a crossscction of the hub and tallic collar l1. On the outer end of the hub axle in the line :t oo. and over the flange (i is a metallic collar 15, Similar letters and figures refer to similar secured b v the screws 16 and provided on the parts throughout the several views. upper surface with a screw-thread.

25 I make a wagon-axle 1, on the ends of which On the spindle 3 and Outside of the flange 75 I make a collar 2, and beyond the collar 2 I G is made a metallic collar 5, turned smooth make a spindle 3, turned down to carry the on the inner surface and grooved with a cage and hub of the wheel. At the outer end groove to carry the metallic balls 7. Outside of the spindle 3 I make a mortise in the meof the collar 5 I make a metallic washer 19,

3o dian line, and in this mortise I make a closeand then a leather or other elastic washer 20, Se fitting wedge 22. To the axle 1 and collar 2 and outside of this a second metallic washer I fit a plate 4 of circular form, through which 21. All these washers are held in place by the spindle 3 passes. This plate I, has, at a the wedge 22. Over all the washers, wedge, convenient point on the face nearest the hub, and collar 5 and balls 7 I spring a spherical 3 5 acylindrieal groove,in which revolves a series cap 23, secured by the nut 2l on the serew- 85 of metallic balls 10. On the circumference of thread on the end of the collar 15. this plate l is secured a metallic cap 11, by Between the end of the collars 17 and 17 screws. I then make a hub A that will fit and the plates 1t and plate 5 I pour a suitable over the spindle 3 and come up against the lubricating compound 18 1S.

4o face of the plate L The center of the hub A, Having thus described the parts of my in- 90 I core ont, and in this core I fit a cage, convention, I proceed to explain the manner of sisting of a collar 17 and 17, grooved on the using the same. I put the parts together in inner side with a series of cylindrical pits such amanner that the series of balls 10 shall carrying metallic balls 2f), which support rollroll in the groove of the plate 1, and the cage 45 ers 25 which bear on the spindle 3 and the containing` the rollers 25 Shall rest in the end 95 inside of the core. The collars 17 17 are seof the hub, the said rollers 25 rolling on the cured together by rods to form the said cage. spindle 3 and the inside of the core of 9, and

About the cage containing the rollers 25 and the balls 7 shall roll in the groove of the plate collars 17 17 I make a metallic cylinder or G and plate or collar 5. I then fill the space 5o core 9, and make a flange S on one end of the between the plates I and the collp 5 and the roo unoccupied space of the core in the center of the hub with a suitable fusible lubricant. I then adjust the washers 19, 20, and 2l and drive in the key or wedge 22 to bring up the whole to an equal bearing, and I then screw on the spherical cap 23 to the collar 15.

I am aware that wagon wheels and hubs with a central metallic core have been used, and it is not my intention to lay claim to a Wagon wheel and hub in the broad sense; but

Vhat I do claim, and desire to secure by Letters Patent, is

1. In an anti-friction journal for vehicles, the combination of an axle having a spindle of uniform diameter with a mortised end and key, and a series of metallic and elastic washers iittin g over the said spindle, and a metallic collar or plate, also fitted over the said spindle and containing a cylindrical groove carrying a series of metallic balls, and a like plate at the other en d of the spindle provided with a series of metallic balls rolling in a cylindrical groove, with a cage consisting of collars fastened together and containing a series of rollers pivoted to the said collars by a metallic ball, the said rollers revolving about the said spindle and the core of the hub, the unoccupied space within the said core being filled with a fusible lubricant, all substantially as andfor the purpose set forth and described.

2. In an anti-friction journal for vehicles,

the combination of an axle and spindle provided with a series of rollers and washers secured with a wedge or key, .the said spindle being provided at one end with a circular grooved plate, in which roll a series of metallic balls, and having at the other end of the said spindle a similar circular plate with a cylindrical groove and a series of metallic balls, with a metallic case or box having a series of ridges and a turned flange Wit-h a cylindrical groove in the outer face carrying or accommodating the metallic balls of the opposite plate and provided at the other end with a flange screwed to the body of the case and bearing a groove, and a series of balls rolling in a groove in the opposite plate, all arranged and operating substantially as set forth.

3. In an anti-friction journal for vehicles, the combination of an axle and spindle provided with a plate having a cylindrical collar or cap of metal screwed to the said plate by screws, with a hub or body of a Wheel having on the inner edge of the said hub aleather collar or band secured to the hub, and which leather collar projects under and revolves Within the said metallic cap on the plate, all substantially as and for the purpose set forth and described.
